Just discovered Dudley's cousin must have come in on my KP rock that I got in 2018. He must have been tiny when the rock arrived because I never saw him until the other night. I haven't noticed him causing any issues but I might have to trap him and put him in the fuge.You should plan for something to come along with any rock cultured in the oceans. My rock stayed in tubs so I could go through before putting in my tank. Dudly made me set up a five gallon tank for him. He was cool. I'd never want to have to tear down a tank to find him.
